Problems solved by technology

[0005] It must pass the rigorous four-ball extreme pressure and anti-wear performance test required by it. At present, most products cannot meet this test requirement.
Although the industry has also done a lot of research work, it cannot fundamentally solve the problem and can only try to persuade Shenlong Company to make concessions on this indicator from the limitations of the method itself, but the industry still has not provided a lubricant solution that fully meets the above requirements.

Abstract

The invention relates to an automobile lubricant. The automobile lubricant comprises the following substances in part by weight: 100 parts of Great Wall Brand SJ10W-40 lubricant or Great Wall Brand SL5W-30 lubricant, 0.30 to 0.39 part of high alkaline sulphonate, and 0.20 to 0.25 part of zinc dialkyl dithiophosphate. Preferably, the automobile oil preferably comprises 0.35 part of the high alkaline sulphonate, and 0.23 part of the zinc dialkyl dithiophosphate. The automobile lubricant can meet the requirements of the standards of Peugeot-Citroen B71 2231, B7 12232 and B71 2233.

Description

technical field [0001] The invention relates to a lubricating oil, in particular to a lubricating oil for vehicles which reinforces and improves extreme pressure and anti-wear properties. Background technique [0002] Shenlong Automobile Company is a car production and management enterprise jointly established by Dongfeng Motor Corporation and French Citroen Company. Its automobile engine loading oil and service oil must meet the requirements of Peugeot Citroen B71 2231, B71 2232 and B71 2233 standards. The extreme pressure and anti-wear performance of lubricating oil has put forward unique technical requirements, and the specific requirements are shown in Table 1: [0003] Table 1 Peugeot Citroen Automobile Company engine oil four-ball engine extreme pressure and anti-wear index requirements [0004] project indicators experimental method Four ball machine test Stuck preload (1500r / min, 60s), N Wear spot diameter (980N, 60s, 1500r / min), mm...
